Department of Homeland Security Secretary John Kelly on Sunday condemned intelligence leaks after the Manchester attack as "darn close to treason," NBC News reported.
"I believe when you leak the kind of information... high, high level of classification… I think it's darn close to treason," Kelly told NBC's "Meet The Press." He added that he didn't know where the leak came from.
In a statement Thursday, President Donald Trump also spoke about the leaks after the attack, calling them "deeply troubling" and asking the Department of Justice to investigate.
The sharing of intelligence between British counterterrorism police and U.S. officials was briefly paused after pictures from the scene of Monday's bombing were published by the New York Times - and authenticated to NBC News by a senior U.S. law enforcement official. The name of the suspected attacker was also leaked.
